The pixel definition layer 108 is disposed on the insulating layer 106to define a configuration position of the light-emitting element 109.For example, a material of the pixel definition layer 108 may include anopaque or translucent polymer material, such as a black resin or atranslucent resin material, but the disclosure is not limited thereto.FIG. 1B is a cross-section corresponding to a section line I-I′ in FIG.1A. As shown in FIG. 1B, the pixel definition layer 108 may be patternedto form a plurality of openings and a plurality of pixel definitionpatterns 108P. The plurality of openings may include a plurality offirst openings A1 and a plurality of second openings A2. The firstopening A1 of the pixel definition layer 108 may define a light-emittingregion (for example, the first light-emitting region E1), for example,the configuration position of the light-emitting element 109. The secondopening A2 of the pixel definition layer 108 may define a transparentregion T. FIG. 1B only shows two openings: the first opening A1 and thesecond opening A2. To make the drawing concise and easy to explain, thepixel definition layer 108 is not shown in FIG. 1A.

According to some embodiments, the thickness of the insulating layerunder the first opening A1 may be greater than the thickness of theinsulating layer under the second opening A2. According to someembodiments, the number of the insulating layers under the first openingA1 may be greater than the number of the insulating layers under thesecond opening A2. To be specific, as shown in FIG. 1B, the insulatinglayer 102, the insulating layer 104, and the insulating layer 106 aredisposed on the substrate 100 under the first opening A1.

For example, the insulatinglayer 102, the insulating layer 104, and the insulating layer 106 formthe opening A3 at a position corresponding to the second opening A2. Theopening A3 of the insulating layer may be overlapped with the secondopening A2 of the pixel definition layer 108 to define the transparentregion T. FIG. 1B shows that in the transparent region T, threeinsulating layers (the insulating layer 102, the insulating layer 104,and the insulating layer 106) form the opening A3 to expose thesubstrate 100. However, according to other embodiments, in thetransparent region T, the opening A3 does not need to expose thesubstrate 100, i.e., at the position of the opening A3, there is stillan insulating layer (not shown) disposed on the substrate 100. Forexample, at the corresponding position of the opening A3, at least oneof the insulating layer 102, the insulating layer 104, and theinsulating layer 106 may be retained.

In someembodiments, although not shown, an electrode pattern may be furtherconfigured on the electron transport layer 109-3.

The filling layer 110 is disposed on the pixel definition layer 108 andcovers the light-emitting element 109. For example, a material of thefilling layer 110 may include an organic material or a polymer material,such as PMMA, epoxy, acylic-based resin, silicone, polyimide polymer ora combination of the above materials, but the disclosure is not limitedthereto. The filling layer 110 may have a single-layer or multi-layerstructure.

It should be understood that the components or film layers in the panel10 may be increased or decreased according to different requirements.For example, when the panel 10 is a micro LED display panel, the panel10 may optionally omit the pixel definition layer 108, but thedisclosure is not limited thereto.

FIG. 1B is a cross-section corresponding to the section line I-I′ inFIG. 1A. As shown in FIG. 1B, in the panel 10, under the structureconfigured with the pixel definition layer 108, a bottom range of thefirst opening A1 of the pixel definition layer 108 may be taken as arange of the light-emitting region (such as the first light-emittingregion E1). To make the drawing concise and easy to explain, the pixeldefinition layer 108 is not shown in FIG. 1A. On the other hand,according to some embodiments, under the structure without the pixeldefinition layer 108, a light-emitting surface of the light-emittingelement 109 (such as a micro LED) may be taken as the range of thelight-emitting region (such as the first light-emitting region E1).

In some embodiments, as shown in FIG. 1A, the panel 10 may furtherinclude a second light-emitting region E2, a third light-emitting regionE3, and a fourth light-emitting region E4, but the disclosure is notlimited thereto. Similar to the aforementioned description, the firstopening A1 of the pixel definition layer 108 may define the firstlight-emitting region E1, the second light-emitting region E2, the thirdlight-emitting region E3, and the fourth light-emitting region E4. Thesecond light-emitting region E2 is located adjacent to the firstlight-emitting region E1 in a first direction D1, the thirdlight-emitting region E3 is located adjacent to the secondlight-emitting region E2 in a second direction D2, and the fourthlight-emitting region E4 is located adjacent to the first light-emittingregion E1 in the second direction D2. The first direction D1 and thesecond direction D2 may be different, and may be intersected with eachother. The first direction D1 and the second direction D2 may both beperpendicular to a normal direction (such as a third direction D3) ofthe substrate 100. For example, the first direction D1 and the seconddirection D2 may be perpendicular to each other, but the disclosure isnot limited thereto.

Although the pixel definition layer 108 is not shown in FIG. 1A,regarding an electronic device with the pixel definition layer, eachlight-emitting region may be defined by the first opening A1 of thepixel definition layer 108, and the transparent region T may be definedby the second opening A2 of the pixel definition layer 108. To bespecific, for example, referring to the fourth light-emitting region E4(A1), the first light-emitting region E1 (A1), and the transparentregion T (A2) indicated along the second direction D2, the two firstopenings A1 of the pixel definition layer 108 may define the fourthlight-emitting region E4 and the first light-emitting region E1, and thefourth light-emitting region E4 (A1) and the first light-emitting regionE1 (A1) are separated by the pixel definition pattern 108P. The secondopening A2 of the pixel definition layer 108 may define the transparentregion T, and the first light-emitting region E1 (A1) and thetransparent region T (A2) are separated by the pixel definition pattern108P.

As shown in FIG. 1A, in an embodiment, the first light-emitting regionE1, the second light-emitting region E2, the third light-emitting regionE3, and the fourth light-emitting region E4 are, for example, a redlight-emitting region, a green light-emitting region, a bluelight-emitting region, and a white light-emitting region, respectively,but the disclosure is not limited thereto. The colors of the firstlight-emitting region E1, the second light-emitting region E2, the thirdlight-emitting region E3, and the fourth light-emitting region E4 areonly an example, and the disclosure is not limited thereto. Theabove-mentioned arrangement sequence of the first light-emitting regionE1, the second light-emitting region E2, the third light-emitting regionE3, and the fourth light-emitting region E4 is only an example, and thedisclosure is not limited thereto. According to some embodiments, onelight-emitting region (for example, one first light-emitting region E1)may define one sub-pixel. According to some embodiments, a plurality oflight-emitting regions (sub-pixels) of different colors may constituteone pixel. For example, the first light-emitting region E1, the secondlight-emitting region E2, and the third light-emitting region E3 maydefine one pixel. For example, the first light-emitting region E1, thesecond light-emitting region E2, the third light-emitting region E3, andthe fourth light-emitting region E4 may define a pixel Px, as shown by adashed frame in FIG. 1A.

In some embodiments, the panel 10 may include a plurality of firstlight-emitting regions E1, a plurality of second light-emitting regionsE2, a plurality of third light-emitting regions E3, and a plurality offourth light-emitting regions E4. The plurality of first light-emittingregions E1 and the plurality of second light-emitting regions E2 are,for example, alternately arranged in the first direction D1. Theplurality of third light-emitting regions E3 and the plurality of fourthlight-emitting regions E4 are, for example, alternately arranged in thefirst direction D1. The plurality of first light-emitting regions E1,the plurality of fourth light-emitting regions E4, and the transparentregions T are, for example, alternately arranged in the second directionD2. The plurality of second light-emitting regions E2, the plurality ofthird light-emitting regions E3, and the transparent regions T are, forexample, alternately arranged in the second direction D2. However, itshould be understood that the color types, the number of colors, orarrangement method of the light-emitting regions in the panel 10 may bechanged according to different requirements, which is not limited tothat shown in FIG. 1A.

The transparent region T is arranged on one side of the firstlight-emitting region E1. For example, in the second direction D2, thetransparent region T is located between the first light-emitting regionE1 and the fourth light-emitting region E4, and there is no otherlight-emitting region (such as the second light-emitting region E2, thethird light-emitting region E3 or the fourth light-emitting region E4)between the transparent region T and the first light-emitting region E1.

As shown in FIG. 1A, the panel 10 may include a plurality oflight-emitting regions and a plurality of transparent regions T. Severallight-emitting regions and one transparent region T may form a displayblock DR. For example, in FIG. 1A, one display block DR may include 8light-emitting regions and one transparent region T, for example, 2pixels Px and one transparent region T. The panel 10 may include aplurality of repeated display blocks DR. As shown in FIG. 2 , thedisplay block DR may include 8 light-emitting regions and onetransparent region T. The numbers of the light-emitting regions and thetransparent region in the display block DR are only an example, and thedisclosure is not limited thereto. As described above, the transparentregion T is defined by the second opening A2 of the pixel definitionlayer 108, and, as shown in FIG. 1B, the second opening A2 is defined bythe pixel definition pattern 108P. Therefore, as shown in FIG. 1A, twoadjacent transparent regions T (for example, two transparent regions Talong the first direction DO may be separated by the pixel definitionpattern 108P. Two adjacent transparent regions T means that there are noother light-emitting regions between the two adjacent transparentregions T. Furthermore, as shown in FIG. 1A, two adjacent display blocksDR (for example, two adjacent display blocks DR along the firstdirection DO may be separated by the pixel definition pattern 108P.According to some embodiments, the pixel definition pattern 108P may notbe provided in the transparent region T in the same display block DR.

The transparent region T may be observed by using an optical microscope.FIG. 2 is a schematic partial top view of a panel in an electronicdevice according to an embodiment of the disclosure. Referring to FIG. 2, the panel 10 includes a plurality of opaque elements, such as adriving circuit DV, a light-emitting element 109, conductive lines CL(such as a signal line, a power line, etc.), a black matrix (not shown),and a black pixel definition layer 108 (not shown in FIG. 2 , referringto FIG. 1B), metal pads (not shown), etc. The aforementioned opaqueelements are arranged in an opaque region NT and located outside thetransparent region T, i.e., the transparent region T does not includethe aforementioned opaque elements. A range of the transparent region Tmay be defined by a range of the opaque region NT. In detail, as shownin FIG. 2 , a boundary of the transparent region T may be defined by theopaque elements in the opaque region NT. For example, edges of theconductive lines CL and/or the light-emitting region may define theboundary of the transparent region T. For example, the boundary of thetransparent region T may be defined by a side of the opaque elementfacing the transparent region T and located at the edge of the opaqueregion NT. In some embodiments, the range of the transparent region Tmay be further defined by a light transmittance or an area ratio of thetransparent region to the light-emitting region. For example, a lighttransmittance of the transparent region T to visible light (such aslight with a wavelength of 400 nm to 700 nm or light with a wavelengthof 550 nm) may be greater than or equal to 60% and less than or equal to99%; or, the light transmittance may be greater than or equal to 60% andless than or equal to 80%. In some other embodiments, one display blockDR includes several light-emitting regions and one transparent region T.An area ratio of the transparent region T to one light-emitting region(such as the first light-emitting region E1, the second light-emittingregion T, the third light-emitting region E3 or the fourthlight-emitting region E4) in one display block DR may be greater than orequal to 1 and less than or equal to 20; or, the area ratio may begreater than or equal to 2 and less than or equal to 8. It should beunderstood that, for the ease of drawing and description, FIG. 1A omitsillustrating the above-mentioned opaque elements. In addition, theboundaries of the plurality of light-emitting regions and the boundariesbetween the light-emitting regions and the transparent region T in FIG.1A may be provided with the pixel definition pattern 108P.

For example, thelight control unit 12 may include a photoelectric material, such asliquid crystal, polymer dispersed liquid crystal (PDLC), dye-dopedliquid crystal (DDLC), an electrochromic material or liquid lens, etc.,but the disclosure is not limited thereto. When the light control unit12 includes liquid crystal, such as electrically controlledbirefringence (ECB) liquid crystal, a phase of the light passing throughthe light control unit 12 may be changed through voltage control toadjust the viewing angle of the electronic device 1. When the lightcontrol unit 12 includes polymer dispersed liquid crystal, a haze of thelight control unit 12 may be changed through voltage control to adjustthe viewing angle of the electronic device 1. When the light controlunit 12 includes dye-doped liquid crystal, a color of the light controlunit 12 may be changed through voltage control to adjust the viewingangle of the electronic device 1. When the light control unit 12includes an electrochromic material, the color of the light control unit12 may be changed through voltage control to adjust the viewing angle ofthe electronic device 1. When the light control unit 12 includes aliquid lens, a block liquid appearance may be changed through voltagecontrol, so as to change a light path to adjust the viewing angle of theelectronic device 1.

Taking the light control unit 12 including liquid crystal as an example,as shown in FIG. 1B, the light control unit 12 may include a substrate120, a substrate 121, and liquid crystal 122.

A material of thesubstrate 121 and the substrate 120 may refer to the material of thesubstrate 100, which will not be repeated. In some embodiments, althoughnot shown, one side (such as a lower side) or the opposite sides (suchas upper and lower sides) of the liquid crystal 122 may be provided witha conductive layer. A tilting direction of the liquid crystal is changedby controlling a voltage of the conductive layer, so as to adjust theviewing angle of the electronic device 1.

In some embodiments, in addition to being overlapped with the firstlight-emitting region E1, the light control unit 12 may also beoverlapped with the second light-emitting region E2, the thirdlight-emitting region E3, the fourth light-emitting region E4, and thetransparent region T. Namely, the light control unit 12 is overlappedwith the first light-emitting region E1, the second light-emittingregion E2, the third light-emitting region E3, the fourth light-emittingregion E4, and the transparent region T in the third direction D3.

Referring to FIG. 3A and FIG. 3B, main differences between an electronicdevice 1A and the electronic device 1 of FIGS. 1A and 1B are describedas follows.

For the convenience of description, some top views of the followingembodiments do not show the range of the display block DR. However, itmay be understood that the panel 10 may include a plurality of theabove-mentioned display blocks DR. As shown in FIG. 3A, in theelectronic device 1A, the panel 10 includes the first light-emittingregion E1 and the second light-emitting region E2. The secondlight-emitting region E2 is disposed adjacent to the firstlight-emitting region E1 in the first direction D1, and a light controlunit 12A extends along the first direction D1 and is overlapped with thesecond light-emitting region E2. The range of one display block DR isnot shown in FIG. 3A. For example, the light control unit 12A mayinclude a plurality of light-shielding elements 123, the plurality oflight-shielding elements 123 extend along the first direction D1, and atleast one light-shielding element (such as a light-shielding element123-1) of the plurality of light-shielding elements 123 is overlappedwith the first light-emitting region E1 and the second light-emittingregion E2 arranged in the first direction D1. In some embodiments, asshown in FIG. 3A, at least another light-shielding element (such as alight-shielding element 123-2) of the plurality of light-shieldingelements 123 may be overlapped with the third light-emitting region E3and the fourth light-emitting region E4 arranged in the first directionD1, and at least one another light-shielding element (such as alight-shielding element 123-3) of the plurality of light-shieldingelements 123 may be overlapped with the transparent region T extendingin the first direction D1, but the disclosure is not limited thereto.

In some embodiments, as shown in FIG. 3B, in addition to beingoverlapped with the light-emitting region (such as the firstlight-emitting region E1), the light control unit 12A may also bepartially overlapped with the transparent region T, for example, thelight-shielding element 123-1 in the light control unit 12A isoverlapped with the first light-emitting region E1, and thelight-shielding element 123-3 in the light control unit 12A isoverlapped with the transparent region T, but the disclosure is notlimited thereto. In other embodiments, although not shown, the lightcontrol unit 12A may not be overlapped with the transparent region T.For example, the light-shielding element 123-3 may be omitted in FIG. 3, and when a viewer views a scene behind the electronic device 1Athrough the transparent region T, the display quality (such as imageclarity) of the scene viewed by the viewer in the transparent area T maybe improved, but the disclosure is not limited thereto. In still someother embodiments, although not shown, the light control unit 12A may beoverlapped with the entire display region (not shown) of the panel 10.In detail, the panel 10 may include a display region, which may includethe above-mentioned light-emitting regions (for example, the firstlight-emitting region E1, the second light-emitting region E2, the thirdlight-emitting region E3, and the fourth light-emitting region E4) andthe transparent region T. For example, the plurality of light-shieldingelements 123 may be arranged on the light-emitting regions and thetransparent region T, thereby improving process convenience.

In some embodiments, as shown in FIG. 3B, the plurality oflight-shielding elements 123 may be disposed on the filling layer 110. Amaterial of the plurality of light-shielding elements 123 may includeblack resin, gray resin, white resin or metal, but the disclosure is notlimited thereto. In some embodiments, the electronic device 1A mayfurther include a cover layer 14. The cover layer 14 is disposed on thefilling layer 110 and includes the plurality of light-shielding elements123.

According to some embodiments, the electronic device may beapplied to a vehicle, and the light control unit may suppress light(upward light) emitted by the panel in a specific direction (forexample, the second direction D2). In this way, since the light in thespecific direction (such as the second direction D2) is suppressed, thelight in the specific direction may be reduced from being reflected bythe windshield, so as to reduce the stray light viewed by the driver,which helps to mitigate the problem of the stray light, and may alsoimprove the quality of the image viewed by the driver to mitigate theimpact on the driver's attention.

In FIGS. 3A and 3B, the electronic device 1A has a first side S1 and asecond side S2 connected to the first side S1, where a length LS1 of thefirst side S1 is greater than a length LS2 of the second side S2, andthe first side S1 is substantially parallel to the extending directionof the light control unit 12A (i.e., the extending direction of thelight-shielding element 123, such as the first direction DD.

In FIG.4A, the first light-emitting region E1, the second light-emitting regionE2, the third light-emitting region E3, and the fourth light-emittingregion E4 may constitute one pixel Px. Two second light-emitting regionsE2 (for example, the green light-emitting regions) may be arrangedadjacent to each other along the second direction D2, i.e., there is noother light-emitting region between the two second light-emittingregions E2. According to some embodiments, by arranging two greenlight-emitting regions adjacent to each other, the display quality suchas image sharpness is improved.

In FIG. 4B, there are two fourth light-emitting regions E4 between twoadjacent first light-emitting regions E1 in the second direction D2,where the first light-emitting region E1 is located between thetransparent region T and the third light-emitting region E3 in the firstdirection D1, and the fourth light-emitting region E4 is located betweenthe transparent region T and the second light-emitting region E2 in thefirst direction D1. In FIG. 4B, the first light-emitting region E1, thesecond light-emitting region E2, the third light-emitting region E3, andthe fourth light-emitting region E4 may constitute a pixel Px. Along thesecond direction D2, two second light-emitting regions E2 (for example,the green light-emitting regions) may be arranged adjacent to each otherand two fourth light-emitting regions E4 (for example, the whitelight-emitting regions) may be arranged adjacent to each other.According to some embodiments, by arranging the two white light-emittingregions adjacent to each other, the display quality such as imagebrightness may be improved.

In FIG. 4C, the panel includes the first light-emitting region E1, thesecond light-emitting region E2, and the third light-emitting region E3,but does not include the fourth light-emitting region E4. The pluralityof third light-emitting regions E3 are arranged in the second directionD2, and there are one first light-emitting region E1 and one secondlight-emitting region E2 between two adjacent third light-emittingregions E3 in the second direction D2, and the one first light-emittingregion E1 and the one second light-emitting region E2 are arranged inthe first direction D1. In FIG. 4C, the first light-emitting region E1,the second light-emitting region E2, and the third light-emitting regionE3 may constitute a pixel Px. The light-emitting regions may bestaggered along the second direction D2. For example, the firstlight-emitting region E1 and the third light-emitting region E3 may bestaggered along the second direction D2, i.e., a center of the firstlight-emitting region E1 and a center of the third light-emitting regionE3 are not aligned in the second direction D2. According to someembodiments, the second light-emitting region E2 and the thirdlight-emitting region E3 may be staggered along the second direction D2.

In addition, a plurality of widths (such as a width T1, a width T2,a width T3, and a width T4) of the plurality of transparent regions maybe, for example, gradually increased or decreased along the firstdirection D1. Taking left-hand driving as an example, by making thewidth T4 to be greater than the width T3, the width T3 to be greaterthan the width T2, and the width T2 to be greater than the width T1, aproblem of reduced light transmittance at a large viewing angle ismitigated. Taking right-hand driving as an example, by making the widthT1 to be greater than the width T2, the width T2 to be greater than thewidth T3, and the width T3 to be greater than the width T4, the problemof reduced light transmittance at the large viewing angle is mitigated.

Each display unit DU may be, for example, a pixelincluding one first light-emitting region E1, one second light-emittingregion E2, one third light-emitting region E3, and one fourthlight-emitting region E4, but the disclosure is not limited thereto. Thedisplay units DU are arranged in interleaving in the first direction D1and the second direction D2.

The first side S1 of the electronic device 1D is substantially parallelto the extending direction of the light-shielding element 123 in thelight control unit 12A. For example, the extending direction of thelight-shielding element 123 is parallel to the first direction D1, andthe light-shielding element 123 may be, for example, overlapped with onefirst light-emitting region E1 and one second light-emitting region E2,or overlapped with one third light-emitting region E3 and one fourthlight-emitting region E4 in the third direction D3.

In an electronic device 1E of FIG. 9 , the panel 10E may include a firstregion R1 and a second region R2. The panel 10E is provided with a lightcontrol unit 12A and a light control unit 12E.

As shown in FIG. 9 , the light control unit 12A disposed correspondingto the first region R1 may be used to limit a divergence angle of lightbeams in the second direction D2, and the light control unit 12Edisposed corresponding to the second region R2 may be used to limit thedivergence angle of the light beams in the first direction D1. When theelectronic device 1E is used in a vehicle, for example, when it is usedas an instrument panel, the first region R1 may correspond to a regionwhere the driver is located, and the second region R2 may correspond toa region where a co-pilot is located. The light control unit 12Adisposed corresponding to the first region R1 may suppress thelarge-angle light beams output from the panel 10E (for example, to limitthe light beams in the second direction D2). In this way, thelarge-angle light beams (relative to the third direction D3) may bereduced from being reflected by the windshield, so as to reduce thestray light viewed by the driver and improve the image quality viewed bythe driver. On the other hand, the light control unit 12E disposedcorresponding to the second region R2 may limit the divergence angle ofthe light beams in the first direction D1, i.e., to suppress the lightbeams in the first direction D1. In this way, the light emitted by thesecond region R2 (in front of the co-pilot) may be reduced from beingviewed by the driver, thereby reducing the impact on the driver'sattention. It should be understood that, in any embodiment of thedisclosure, the electronic device may include a single light controlunit to limit the divergence angle of the light beams in a singledirection, or the electronic device may include multiple types (twotypes as shown in FIG. 9 or more types) of light control units to limitthe divergence angle of the light beams in different directions.
